Anthurium siccisilvarum K.Krause

• Genus: Anthurium
• Botanical Background: Described by K. Krause, a notable botanist in early aroid research, the species has contributed to a deeper understanding of habitat adaptation within the Anthurium genus; its study has helped clarify relationships within the family.

• Geographical Range: Native to select tropical regions where dry forests prevail; its distribution is relatively localized, with populations found in areas that undergo marked dry seasons.
• Environment: Thrives in environments with seasonal moisture; typically grows in well-drained soils in areas that experience a mix of high humidity during wet seasons and drier conditions during the off-season, often in lightly shaded understory settings.

Leaves

• Broad, somewhat leathery
• Elliptic to heart-shaped
• Deep green with subtle variegation or texture

Inflorescence (Spadix & Spathe)

• Comprises a spadix accompanied by a modestly sized spathe
• Not notably fragrant
• Color contrast between the spathe and the surrounding foliage can be a visual attraction
• Structure is adapted to attract specific pollinators

Growth Habit

• Primarily terrestrial, growing from a robust rhizome
• Growth pattern does not generally include climbing or epiphytic tendencies, distinguishing it from some other members of the genus

Light Requirements

• Bright, indirect light
• Direct sunlight can scorch the leaves, while too little light may stunt its development

Watering & Humidity

• Maintain consistent soil moisture without overwatering
• High ambient humidity

Soil & Potting Mix

• A well-aerated, organic-rich potting mix that drains effectively is ideal
• An organic-rich, loose medium supports its growth and mimics natural conditions

Temperature & Fertilizer

• Between 65°F and 80°F (18°C to 27°C)
• Balanced, water-soluble fertilizer applied monthly

Division and Cuttings

• Division of the rhizomes
• Carefully separate sections of the plant during repotting to ensure each division has viable roots and a growing tip

Seeds

• Less common due to the lower viability and more specialized germination requirements
• Need a warm and humid environment to germinate successfully

Typical Issues

• Spider mites and mealybugs
• Risk of root rot if overwatered

Treatment Recommendations

• Use mild insecticidal soap or neem oil
• Maintain a careful watering schedule and ensure good airflow

• Adaptation to seasonal dryness makes it an unusual member of the typically humid-loving aroids
• Distinctive growth habit and foliage texture have sparked interest among botanists and plant collectors

• Prized for its rarity and the unique contrast it offers compared to more common, high-humidity aroid species
• Its ornamental value is enhanced by its intriguing leaf structure and modest yet attractive inflorescence

Wild Population Status

• Wild populations of this species are relatively limited
• While it is not widely listed as endangered, localized habitat pressures may warrant monitoring by conservationists

Market Availability

• Not commonly found in mainstream nurseries
• Usually considered a specialty species among advanced collectors and botanical enthusiasts
